Recirculation of energetic particles in Jupiter's magnetosphere

Technical Report ·
OSTI ID:7187377
Angular distribution studies based on the low-latitude Pioneer 10 data and a confirmatory analysis of Pioneer 11 data show that there exists a region in the near equatorial Jovian magnetosphere within which energetic electrons form strongly field-aligned and bisymmetric pitch angle distributions ('dumbbell' distributions). This region encompasses the transition zone between the dipolar inner magnetosphere and the highly distended magnetodisc. The angular distributions of energetic protons in this same region are approximately isotropic. The existence of a significant asymmetry in the field-aligned component of the particle distributions in the high-latitude regions of this L-space is discussed. (GRA)
